I have found more times than not diet and exercise is a formula for failure. There are certainly exceptions to every rule but if you look at the average gym rat they experience more failures, more disappointments and create more life stress than success.
I believe anyone can experience a higher degree of success by stopping the diet and exercise treadmill, going no where. Instead develop a new level of LIFESTYLE. A regimen of diet and exercise requires commitment and dedication. Unfortunately the majority of us just do not have the discipline to follow a diet and exercise regimen but we all can live a different lifestyle. A lifestyle is second nature and easy to follow.
This is a key factor in my personal development and one that I share with those I train.
If you are seriously looking to improve your success rate in your personal development I recommend you consider your lifestyle.
Method (Time + Constancy) = Results
Method is the multiplier because it has the greatest impact on results.
